ABSTRACT
In this study, benzo(a)pyrene-water-oxygen systems were investigated in wide ranges of change
of temperature value and initial components to predict in which conditions benzo(a)pyrene
degraded into more harmful substances. Consequently, the thermodynamic parameters of the benzo(a)
pyrene-water-oxygen system were calculated and the concentration distribution of carbon, hydrogen and
oxygen-containing particles in the gas phase were established. Adding water into the system allowed
decreasing of carbon and acetylene. These elements are the key elements of benzo(a)pyrene formation.
According to this, the main parameter for reducing the concentration of benzo(a)pyrene in the gas phase
was the water content in fuel oil within 10-15%.
Determination of the concentration of benzo(a)pyrene in samples of flue gases of DKVR-4/13 and PTVM- 30M boiler units of the Teplokommunoenergo heating organization of Bishkek city was carried out by chromatographic method. Concentrations of benzo(a)pyrene were found to compare the product of burning ordinary fuel oil and water fuel emulsion. Homogenization of the fuel-air mixture by adding water to the fuel oil allowed us to obtain an inverse emulsion and reduce the concentration of benzo(a)pyrene in flue gases up to 62%. According to this, a new process flowsheet of water fuel emulsions production was proposed for the heating organization.
